Although vitamin B12 can be obtained from the diet, deficiency is not uncommon, particularly among older individuals. Supplementation with methylcobalamin is indicated in such cases. This active molecule is also recommended for vegetarians and vegans, because foods that contain it are often animal-source, such as offal and seafood. Dietary supplements may, therefore, be necessary for those following a vegetarian or vegan diet.

Given the crucial roles vitamin B12 plays in the body, it’s essential to ensure an adequate intake of this vitamin, particularly as a shortfall may result in insufficient production of haemoglobin which is vital for transporting oxygen to red blood cells. If this is not addressed, it can lead to anaemia which is characterised by abnormally low levels of haemoglobin. In vitamin B12 deficiency anaemia, red blood cells are usually bigger than healthy ones. Generally known as macrocytes, these larger red blood cells do not permit adequate oxygen transport, resulting in poor oxygenation of the body. This manifests in various symptoms such as pale skin, a rapid heart rate, severe fatigue, breathing difficulties and headaches. Vitamin B12 supplementation may thus be necessary to prevent deficiency or combat the symptoms of anaemia.

Often underdiagnosed, magnesium deficiencies are common. While the recommended daily intake is about 400 mg, it is estimated that 75% of the population has insufficient magnesium intake. These magnesium deficiencies can be associated with modern diets composed of refined products, as well as increased stress. Other factors can also explain these deficiencies, such as daily overexposure to noise, taking certain medications (diuretics), or an excess of dietary fats or alcohol.
